Okay- this is definitely a different kind of review. As can be evidenced from this thread, I'm a big fan of Scooby-Doo and I like to watch the various cartoons. However, the history of Scooby-Doo can be confusing to follow. I have been working on compiling a list that will review the various video releases Scooby-Doo shows have received, which will hopefully help make it easier to keep up with all the various Scooby-Doo shows and their availability on DVD. (I am also including a few other formats here and there as I run across some evidence of release in that format- namely VHS and also some LaserDisc. If I happen to find any Betamax or CED or Reel-to-Reel releases, etc. I will certainly include them. )
Keep in mind that while I have included a few Region 2 DVD releases and PAL VHS releases, this list is largely based on Region 1 DVD and NTSC VHS releases. I do not claim that this list is all comprehensive, as I know there are a number of video releases that I have not listed. In the case where a series has been given a Complete Series DVD release, I will generally just list that release and not bother to list other DVD releases that have been made that just have a couple of episodes from the series. Also, some episodes have been released on multiple DVD sets, and I may not list all of them, particularly if a later release incorporates those same episodes on it. (For example: The "Scooby-Doo! Winter Wonderdog" DVD release contains episodes that are all duplicated on the later "Scooby-Doo! 13 Spooky Tales: Holiday Chills and Thrills" DVD release- and that release contains additional episodes as well. So I would probably just list that release rather than the earlier one.)
I will try to list VHS releases as well when I get a chance to update this list. At this point, there are still some episodes of various series that have received a VHS release, but still have not made it to DVD, so I will particularly try to highlight those cases.
I hope this will be helpful for other Scooby fans seeking to complete a collection of Scooby-Doo cartoons, or just for casual fans who would enjoy reading through the history of the Scooby-Doo cartoons.
Please note that I have not listed all the various Scooby-Doo movies, whether theatrical, TV-movie or straight-to-video. That would be a much longer list and those are all generally available on either VHS or DVD in any case. (With some exceptions, like in the case of parody/comedic specials aired by Cartoon Network and Hanna-Barbera anniversary specials, etc. I may try to catalog those at some point as well, but I am not primarily focusing on those right now.)
And with that said- enjoy! Scooby Dooby Doo!

1.
“Scooby-Doo Where Are You!” (Complete 1st. and 2nd. Seasons) set (i.e. Complete original series) DVD set

“Scooby-Doo Where Are You!”(Complete 3rd. Season) DVD set (i.e. 16 additional later episodes originally aired under the “Scooby-Doo Where Are You!” titles- really the third season of the show known in syndication as “The Scooby-Doo Show”)

2.
"The Best of The New Scooby-Doo Movies" DVD set (contains 15 episodes).
For the following 9 episodes, the rights from the guest stars could not be otained in order for the episodes to be included on the DVD release.

Though not available on DVD yet, some of these episodes have been officially released to VHS:

"Wednesday is Missing (AKA Scooby-Doo Meets The Addams Family)"- released as "Scooby Doo Meets The Addams Family" by Worldvision, most likely somewhere in the late '80s.- (Note: This is a PAL only VHS release.[i.e. Region 2])

"The Secret of Shark Island" (guest starring Sonny & Cher)- released on the VHS videotape entitled "Hanna Barbera Personal Favorites: Scooby-Doo" (Note: This one has been released both in NTSC and PAL format. It was also released on LaserDisc.
http://www.lddb.com/laserdisc/01621/ID6615HA/Scooby-Doo:-Hanna-Barbera-Personal-Favorites-(1969)
This release also contains the following episodes- "Scooby-Doo, Where Are You"- "What A Night for a Knight" [released on DVD on "Scooby-Doo, Where Are You" Season 1 DVD set], "The Richie Rich/Scooby-Doo Show"- "Scooby Gumbo" [short] [released on DVD on "Scooby-Doo: 13 Spooky Tales: For The Love of Snack" DVD], and "The New Scooby and Scrappy-Doo Show"- "Wizards and Warlocks".

"The Secret of Shark Island" episode was also released as an episode by itself on PAL VHS.

Also: The two episodes to guest star Batman and Robin have been given separate DVD and VHS releases in the early 2000s, but there was also a 1989 public domain VHS release from Worldvision's Kids Klassics label, featuring one of those episodes ("The Caped Crusader Caper"). I just thought the cover art was great and wanted to post it. You can see the front, back and the videotape itself on this page too.

(Of course, this episode is available on DVD too on "The Best of The New Scooby-Doo Movies" DVD set. It is also worth noting that this VHS contains the original intro for the show [featuring various guest stars], rather than the edited version [which excises all guest stars] that appears on later VHS and DVD releases.)

"Ghastly Ghost Town" (Guest Starring The Three Stooges) released on "Scooby-Doo in Ghastly Ghost Town" VHS (PAL only). A Kaleidoscope series release from The Video Collection, catalogue number VC1021, according to this page. [You can see the cover there too.] Released in November 1985. The site also offers a synopsis for the videotape: "Scooby-Doo, a giant-sized but not-too-brave dog, is the mascot of a group of high school students who are fascinated with the mysterious and the occult. Forming a club called Mystery, Inc., they set out to solve perplexing mysteries, having lots of fun and laughter along the way! In 'Ghastly Ghost Town' the members of Mystery, Inc., are forced to seek help on foot in the desert after their van is forced into a sand pit by a low-flying, king-sized bat. in doing so, they come across The Three Stooges, who are really the ones in need of help..."
It's also listed on Amazon.co.uk and you can see the front and back covers of the VHS box there.
This VHS tape was also released in a "Scooby-Doo- Video, Watch and Play Colouring Pack" in England as well. The VHS tape was repackaged in a new box along with a colouring book and felt tip pens. The front and back covers can be viewed at this page on Amazon.co.uk

It also includes the "Hanna Barbera Fun Safety Tips" segment made for video releases.

The second season was renamed “The New Scooby-Doo Mysteries”, which still maintained the same format and cast, but also had Fred and Velma making guest star appearances in six episodes. All of their episodes are two-part in that they take up the entire half hour. Every other episode follows the same format of two 11 minute shorts per half hour episode.)

9.
“A Pup Named Scooby-Doo” – Complete 1st. Season DVD set and Complete 2nd., 3rd. and 4th. Seasons DVD set. (Note: This series returned to the original premise of [usually] facing off with criminals masquerading as a supernatural character.

10.
“What’s New Scooby-Doo?”- Complete 1st. Season DVD set, Complete 2nd. Season DVD set and Complete 3rd. Season DVD set (Note: This series depicted the original gang- Fred, Daphne, Velma, Shaggy and Scooby as their teenage selves, solving mysteries with criminals masquerading as supernatural entities. Some of the clothing for the gang is tweaked here and there, with the same basic color scheme staying the same. Also, the show is clearly set in the early 2000s, which is when it was made.)

11.
“Shaggy and Scooby-Doo Get A Clue!”- (Note: This series is also clearly set in the mid-to-late 2000s, which is when it was made. Shaggy and Scooby-Doo are the only main characters from the original gang on this show. Fred, Daphne and Velma all make appearances in a few episodes, but they mainly play cameo roles. However, their silhouettes can still be seen in the opening credits. Shaggy and Scooby inherit a mansion from Shaggy’s rich uncle and armed with technological advances to the Mystery Machine and superpower-enabling Scooby Snacks, they fight against the criminal plans of recurring villain Dr. Phibes.)

12.
“Scooby-Doo! Mystery Incorporated”-(Note: This series returned to the original premise of fighting criminals masquerading as supernatural entities with the original gang of Shaggy, Scooby, Fred, Daphne and Velma. This series is also unique because it had an ongoing story arc for each season. Guest stars were also seen at times, like Captain Caveman, The Blue Falcon and Dynomutt, Jabberjaw, Speed Buggy and The Funky Phantom.)
Complete Season 1 DVD set. (The Complete Season 2 DVD release has been done in 2 volumes thus far and on October 7, 2014, the Complete Season 2 DVD set was released. The entire series is available on DVD.)

"The Flintstones and Friends in Wacky Wayfarers"1990 VHS release (Hanna-Barbera Superstars banner release)- Has a run time of 85 minutes and features The Flintstones, Wally Gator, Hokey Wolf and Lippy The Lion, as well as Scooby-Doo! (The cover art features both Scooby and Scrappy, so I'm thinking there may be a "Scooby and Scrappy-Doo" 11 minute short on there, but I don't know for sure.)

"Peter Potamus and his Pals in Hippo to Go" 1990 VHS (released under the Hanna-Barbera Superstars banner)-
(view cover here.)
The portly hippo stars in "Stars on Mars," "Monotony on the Bounty" and "America or Bust." Also features episodes with Scooby-Doo, Yogi Bear, Lippy the Lion and Hokey Wolf. Contains cartoon trivia. Runtime is 85 minutes.
Scrappy-Doo is featured on the cover, so it leads me to think that most likely one of the Scooby-Doo and Scrappy-Doo 11 minute long cartoons is included on this videotape, but I am not sure which one.

"Peter Potamus and his Pals in Rib-Ticklin' Travels" VHS (released under the Hanna-Barbera Superstars banner)- [Description from the back cover]
"There's time-warp wackiness afoot as Peter Potamus and his pal So-So travel back to the wild frontier in "Mask Task". Then, Peter lands in the days of dinosaurs in "Wrong Time No See". You'll also head to the big city with Yogi Bear, try your paw at hang-gliding with Scooby-Doo and embark on other terrific trips with Auggie Doggie, Quick Draw McGraw and more!
PLUS, an all-new assortment of HANNA-BARBERA CARTOON TRIVIA, FUN & GAMES to tickle your funnybone and test your animation I.Q.!"
Runtime is 85 minutes.
Yogi Bear, Wally Gator and of course, Peter Potamus and So-So are all featured on the cover, along with Scooby-Doo and Scrappy-Doo. With Scrappy being included on the cover, it leads me to think that most likely one of the Scooby-Doo and Scrappy-Doo 11 minute long cartoons is included on this videotape, but I am not sure which one.

I found another video collection of Scooby-Doo cartoon theme songs on Youtube. Unfortunately, this one has an annoying anime logo on the bottom right hand corner of the screen throughout it.
On the plus side, this one does include "Shaggy and Scooby-Doo Get A Clue!"
(But it doesn't include the second season opening for "Scooby-Doo Where Are You!" or the opening for "The Scooby-Doo/Dynomutt Hour".)
But it also remembers to include "Scooby's All Star Laff-A-Lympics", "The Richie Rich/Scooby-Doo Show" and "The Scooby & Scrappy-Doo Puppy Hour".

And here's something else cool I found- a fun video tribute to Scooby-Doo, Vincent Price and Michael Jackson's "Thriller".
(Seeing as how the opening of "The New Scooby-Doo Mysteries" pretty obviously referenced The King of Pop's "Thriller" song, it's cool and fitting to see this mashup.)

I have just recently found the episode listing for one of the "Scooby-Doo and Scrappy-Doo" VHS tapes, so that is updated. I am continuing to update this thread as I find out more information on DVD or VHS releases.

This site has some great, cool posters from Worldvision's Kids Klassics label, featuring some of the Scooby-Doo VHS releases I've covered here, along with many other Hanna-Barbera classics!
(There is also a poster for Bible videos- I am wondering if these are public domain releases of Hanna-Barbera's "The Greatest Adventure: Stories from The Bible" video series or not though. That is one of my all-time favorite Bible cartoon series (and Christian-themed series in general) and a H-B '80s classic.)

Also, I can't make out what all these titles are, but I found a cool page of VHS releases from the 1980s onward and it looks like the page is in Swedish- so I presume these would all be PAL releases.

I have the Scooby Doo Snack Tracks CD, and would recommend it if you happen across it, all the classic chase and montage music.

The bible cartoons do have DVD releases in the UK, though, they are all separate and not in a set. I used to know a good reference site for US public domain titles, but can't recall it now. I am sure the google could find one or two though.

Oh yeah- the numerous Scooby-Doo cartoon series and the various Superfriends cartoon series are both some of the most confusing ones to follow! (And I'm a fan of both and I know I've gotten confused many times trying to follow the airing histories not to mention the sporadic video release histories!)
At least Superfriends is finally complete on DVD now.
Scooby-Doo is getting closer to that for many of the different series- but as you can see, there are still a number of late '70s and early '80s series that still have not gotten complete DVD releases. (And at least one mid-2000s series that seems unlikely to get further releases either- though I do hope they all make it to DVD eventually.)
I hope this thread is helpful for other Scooby fans- it's been helpful for me just to sort out what DVD and VHS releases are out there so I can know which ones I might want to track down..... (And to get an idea of what episodes are available commercially where.)
I have heard of the Scooby-Doo Snack Tracks CD; maybe I will look into that one- it definitely sounds pretty cool.

Thanks for the tip about The Greatest Adventure: Stories From The Bible series. It's nice that it's gotten a full DVD release in Region 2; it'd be nice to see Region 1 get a full DVD release. There are some episodes available on DVD in the USA- but again, it's sporadic and certain episodes are still not available yet. Of course, given the nature of this direct-to-video series- needless to say, all the episodes have been released to VHS at least.

Just added a few newly discovered Hanna-Barbera VHS releases. They did a number of combination VHS tapes that featured a variety of their characters- and some of these themed releases feature Scooby-Doo! One of the ones I listed today- "Rompin' Romance", actually features a Yabba-Doo segment that has not been released to DVD yet!
Of course, ultimately I'd love to see all these various Scooby-Doo cartoons get complete DVD season releases- but until that happens, it's good to know that at least there are some official VHS releases out there to track down that have some of the missing cartoon episodes.

Thanks, Ice Dragon. It has definitely taken some time and work to compile- but it's a project of personal interest for me as a long time Scooby-Doo fan. Yeah, Teenage Mutant Ninja Turtles has had a long and interesting history too- but I don't think its video release history is quite as confusing- lol. And at least it's finally complete on DVD with all of the 1980s cartoon series being released now. (And the live action series for that matter, and I believe the 2003 series as well. The 2012 series is getting releases on DVD too.) Now if only we could get the "Turtles Coming Out of Their Shells Tour" VHS video and "Making Of" special VHS to DVD.... And that Turtles Christmas VHS tape all on DVD.

Hey... I dont know if this is actually going to improve your hard dedicated list, but I'm going to post it anyway, hoping that you may find an use for it:

I just found this spanish releases:

You see? these are VHS releases found at my local market. Too bad the seller did not write a review to see what they are actually about. But one of them pointed out that those tapes never got a DVD release.

Cool! Thanks so much, Ice Dragon.
I know a little Spanish and that combined with the cover image, I'm pretty sure the first one is "Scooby-Doo Meets The Boo Brothers". But you never know, especially with releases around the world- I've found that sometimes there can be additional cartoons added along with the main feature- it's always good to check the runtime just in case.
The second video is "Scooby-Doo's All Star Laff-A-Lympics". And the third one is the most recent DVD in the "13 Spooky Tales" series- "Field of Screams". And yes, I'm certainly interested in DVD releases, along with VHS releases- but I'm also interested in LaserDisc releases (particularly those that have episodes not available anywhere else yet) and Beta releases, 16 mm film reel releases, etc.

I certainly appreciate any help in compiling this list.

Well, it took some searching, but I finally found the list of episodes included on the "Scooby & Scrappy-Doo" LaserDisc released in the UK, which I've added in my original post. Many of those episodes have not been released to DVD yet, so for those with LaserDisc players in the UK, this would be a great item for Scooby fans to track down.
And as it turns out, that release was also issued in Betamax and VHS videotape formats too.

I've been excited to recently run across a nice slew of classic Hanna-Barbera VHS releases at thrift stores in the area and my Scooby-Doo find was the compilation video "Hanna-Barbera's Festival of Fun"- a VHS tape with 6 hours' worth of cartoons!
I have updated the entry for this VHS tape with a full list of episodes. It has two "Scooby and Scrappy-Doo" shorts on it (both of which are already available on DVD), but nonetheless- it has a number of other H-B cartoons that I don't think are on DVD yet. So it's well worth it for that and it's a great tape to watch if you want a smorgasbord of classic Hanna-Barbera cartoons, ranging from the 1950's through the 1960's and 1970's and, because of the inclusion of the Scooby and Scrappy shorts, into the early 1980's.
I've also added yet another Hanna-Barbera compilation VHS videotape I've run across that includes some Scooby and Scrappy shorts- but I'm not sure which ones. As I find more details on this and other videos (or other videos altogether that I don't have listed yet), I will keep updating the post.
